'''Mortality rate''', or '''death rate''',<ref name=Porta-2014>{{cite book|editor-last=Porta|editor-first=M|title=A Dictionary of Epidemiology| chapter-url=https://books.google.com/books?id=okf1AwAAQBAJ&pg=PA69|year=2014|edition=5th|publisher=Oxford University Press|location=Oxford| isbn=978-0-19-939005-2|pages=189, 69, 64, 36|chapter=Mortality Rate, Morbidity rate; Death rate; Cumulative death rate; Case fatality rate}}</ref>{{rp|189,69}} is a measure of the number of [[death]]s (in general, or due to a specific cause) in a particular [[Statistical population|population]], scaled to the size of that population, per unit of time. Mortality rate is typically expressed in units of deaths per 1,000 individuals per year; thus, a mortality rate of 9.5 (out of 1,000) in a population of 1,000 would mean 9.5 deaths per year in that entire population, or 0.95% out of the total. It is distinct from "[[morbidity]]", which is either the [[prevalence]] or [[Incidence (epidemiology)|incidence]] of a [[disease]], and also from the [[incidence rate]] (the number of newly appearing cases of the disease per unit of time).<ref name=Porta-2014/>{{rp|189}}{{verification needed|date=January 2020}}

An important specific mortality rate measure is the '''crude death rate''', which looks at mortality from all causes in a given time interval for a given population. {{As of|2020}}, for instance, the [[Central Intelligence Agency|CIA]] estimates that the crude death rate globally will be 7.7 deaths per 1,000 people in a population per year.<ref name=CIA2020>{{cite book | author=CIA Staff | date=2020 | title=CIA World Factbook | chapter=People and Society | chapter-url=https://www.cia.gov/library/publications/the-world-factbook/fields/346.html#XX | access-date=January 31, 2020 | archive-date=October 10, 2020 | archive-url=https://web.archive.org/web/20201010211308/https://www.cia.gov/library/publications/the-world-factbook/fields/346.html#XX | url-status=dead }}</ref> In a generic form,<ref name=Porta-2014/>{{rp|189}} mortality rates can be seen as calculated using <math>(d/p) \cdot 10^n</math>, where ''d'' represents the deaths from whatever cause of interest is specified that occur within a given time period, ''p'' represents the size of the population in which the deaths occur (however this population is defined or limited), and <math>10^n</math> is the conversion factor from the resulting fraction to another unit (e.g., multiplying by <math>10^3</math> to get mortality rate per 1,000 individuals).<ref name=Porta-2014/>{{rp|189}}
